A new drone developed by a team of scientists will simply melt away to conceal it's spying activities.
Drones are everywhere it seems. They've been used for military purposes for quite some time, but the smaller commercial versions appear to be pretty common now, used by photographers, filmmakers, or enthusiasts. However, have you ever wondered why nobody has made one out of mushrooms? No? OK, well they've done it anyway.
There is a purpose to a mushroom-based drone, of course. Researchers from a number of educational institutions along with NASA's Ames Research Center in California created the biodegradable drone to cover your tracks after spying. So, if you were to lose the drone for instance, you'd be fairly safe in the knowledge that it would degrade out of existence. Lynn Rothschild of NASA Ames said, "no one would know if you'd spilled some sugar water or if there'd been an airplane there."
The prototype is made up of a root-like fungal materical called mycelium. This material was cultivated into its drone shape by Ecovative Design, a New York based company that grows the fungas as an eco-friendly alternative to plastic packaging.

As you may expect, not all of the drone's parts are biodegradable, particularly its battery, rotors, and controls. But, they have managed to print the circuitry of the drone in silver nanoparticle ink, which will disintegrate with the body of the drone.
